Are there any formal techniques for refactoring SQL similar to this list here that is for code?
I am currently working on a massive query for a particular report and I'm sure there's plenty of scope for refactoring here which I'm just stumbling through myself bit by bit.
Why is the ( ) mandatory in the SQL statement
select * from gifts INNER JOIN sentgifts using (giftID);
? The ( ) usually is for specifying grouping of something. But in this case, are we supposed to be able to use 2 or more field names... in the example above, it can be all clear that it is 1 field, is it just that the parser is not made to bypass the ( ) when it is all clear? (such as in the language Ruby).
I am using Castle ActiveRecord as my ORM. When I try to store unicode strings, I get question marks instead.
Saving unicode strings worked perfectly when I was using mysql, but when I recently switch to SQL Server it broke. How should I go about fixing this?
Hi,
I have recently discovered the tablediff utility of SQL Server 2005.
I have 2 instances of the same database each on a different server.
Is it possible to compare all tables using tablediff without having to replicate the same command while only changing the table name?
For example, compare table1 on server1 with table1 on server2 then compare table2 on server1 with table2 on server2, until all tables have been compared.
Is it possible to write a plugin or a form for SQL Server Enterprise Manager version 8? I'm doing some simple queries all the time to admin the databases. So wondering if I could write something for it.
Hi,
I just noticed that if I have an identity column in a table, when I insert new rows MS SQL 2008 is automatically filling up the sequence if there are discontinuity. I mean, if in my identity column I have 1,2,5,6 if I insert other two rows in the table the system puts automatically 3,7 in the identity column.
Do you know how to control this behavior?
THANKS
Is there a tool around that would produce a diagram showing existing tables and their relationships given a connection to a database or by any other means?
This is for SQL Server 2008 Express Edition.
I'm doing a little digging and looking for a explanation on how SQL server evaluates MIN(Varchar).
I found this remark in BOL: MIN finds the lowest value in the collating sequence defined in the underlying database
So if I have a table that has one row with the following values:
Data
AA
AB
AC
Doing a SELECT MIN(DATA) would return back AA. I just want to understand the why behind this and understand the BOL a little better.
Thanks!
I have an application which intensively uses DB (SQL Server).
As it must have high performance I would like to know the fastest way to insert record into DB.Fastest from the standpoint of execution time.
What should I use ?
As I know the fastest way is to create stored procedure and to call it from code (ADO.NET).
Please let me know is there any better way or may be there are is some other practices to increase performance.
Any experiences on how to document Entity Framework 4 based Database projects?
There is the Document and Summary properties on the Entities, but if we want to regenerate the model from the database at some point, it will be lost!
Is there some way to map documentation data inside SQL to the Entities in the EDMX file so it is safe.
Suggestions of other best practices? Ideally I want to be able to augo generate html/helpfile documentation from the DB when we deploy.
I have an sql statement that returns this result below,and I want that the num will drag the latest(by date) num that is not null. I can't get it right.
I want to add somthing like this:
case
when num is null then max(num where date<my_date)
my result now:
Date num
1.1 0
2.1 1
3.1 NULL
4.1 NULL
5.1 4
what I want:
Date num
1.1 0
2.1 1
3.1 1
4.1 1
5.1 4
For Data Explorer I would like to add support for a Batch separator.
So for example if users type in:
select 'GO' go select 1 as go
Go
select 100
I would like to return the three result sets.
Its clear that I need some sort of parser here, my hope is that this is a solved problem and I can just plug it in. (writing a full T-SQL parser is not something I would like to do)
What component / demo code could achieve splitting this batch into its 3 parts?
Situation:
Running a report on SQL Server Reporting Services
When I do a Preview of the Report all my charts look fine. No problems.
When I run a subscription for the report, the chart look different. Like completely different legends are gone etc.
Any ideas what the cause would be?
BTW the charts are Dundas Charts.
Im using Native SQL from ABAP language. The query to get data is something like this
SELECT COUNT(ROWID)
FROM <SCHEMANAME>.<TABLENAME>;@<DATABASENAME>
INTO :localvariable
I want to somehow set the schemaname and database name as default so that i do not need to use them in the SELECTs later. Then i can only use the table name in the SELECT.
thanks !!

The following SQL query isn't working. I think the error is on the first line.
SELECT SUBSTRING(tbl_news.comment, 1, 250) as tbl_news.comment,
tbl_news.id, tbl_news.date, tbl_news.subject, tbl_users.username FROM tbl_news
INNER JOIN tbl_users ON tbl_news.creator = tbl_users.id
ORDER BY date DESC
Hi,
I'm trying to do some work with my SQL table.
I have 2 buildings with room numbers 1 - 100 in building 1 and 101 - 199 in building 2.
I have a location field (which I've just created) and want to run a query to populate it with either 'Building 1' or 'Building 2' depending on which room number it has in the 'Room' field.
Many thanks for your help.
Regards
Scott
I have a SQL Server 2008 database with 300 tables. The application I have to design is an Windows Forms app, .NET 3.5, C#.
Which is the best way to work with LINQ2SQL ?
I intend to make a datacontext for each business entity.
Is there any problem ?
I need to know if this way of working with LINQ has any disadvantage or can create performance issues ?
Thanks.
I have been playing around with creation of pdf documents for a project that I'm working on. I would like to store the generated pdf document in a SQL database and then later be able to retrieve this pdf as well.
What are some suggestions for doing this? Can the document be stored in the database without physically creating the document on the server?
I am trying to compare a series of strings like the following
rodeo rodas
carrot crate
GLX GLX 1.1
GLX glxs
the comparision need not be case sensitive
i am trying to write a sql where i am updating the first string with the second string if they match approximately. Here except the second string all the other examples match. I would like to write a query which updates the strings except the second one.
is this possible directly in a query in ACCESS
thanks
I have the following table...
TABLE: Accounts
ID (int, PK, Identity)
AccountType (int, PK)
Username (varchar)
Password (varchar)
I have created a composite key out of ID and AccountType columns so that people can have the same username/password but different AccountTypes.
Does this mean that for each foreign table that I try and link to I'll have to create two columns?
I’m using SQL Server 2008
In my 2nd ASP.NET MVC project I'm facing a very weird problem: when I call the SubmitChanges method of the DataContext class, nothing updates in the database. It's weird because everything works fine with my first project.
I'm using a remote database created in Sql Server Management Studio, I tried doing some queries there and in Visual Studio 2010 (where I have the connection to the database), they all work.
Where might the problem be hidden?
